laparoscopic radiofrequency ablation

BACKGROUND: Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the two most common malignant neoplasms of the liver. The objective of this study was to assess outcomes of surgical approaches to liver ablation comparing laparoscopic versus percutaneous microwave ablation (MWA), and MWA versus radiofrequency ablation (RFA) in patients with HCC or CRLM lesions smaller than 5 cm. METHODS: A systematic review was conducted across seven databases, including PubMed, Embase, and Cochrane, to identify all comparative studies between 1937 and 2021...

INTRODUCTION: Alpha-fetoprotein (AFP) can become elevated in hepatocellular carcinoma (HCC), yolk sac tumors and other malignant tumors of various organs. Herein, we present a case of AFP-producing gallbladder carcinoma with signet ring cells successfully treated with laparoscopic whole-layer cholecystectomy. PRESENTATION OF CASE: A 69-year-old woman was found to have increased levels of the tumor marker AFP (16.1 to 1474 ng/mL), and an irregularly shaped mass 22 mm in size in the gallbladder at 5 months follow-up after transcatheter arterial chemoembolization and radiofrequency ablation for HCC in segment 3 of the liver...

BACKGROUND: Bevacizumab combined with fluorouracil is the currently recommended maintenance treatment for metastatic colorectal cancer, but the use of bevacizumab needs to be carried out in hospitals, which invisibly increases the risk of patients' exposure to coronavirus disease 2019 (COVID-19) during the COVID-19 epidemic. Therefore, except of the advantage of convenience, all oral drugs as the maintenance treatment can reduce hospitalization and potential exposure risk during the COVID-19 epidemic, which is worth further exploration...

PURPOSE: Primary Aldosteronism (PA) is increasingly considered as a common disease affecting up to 10% of the hypertensive population. Standard of care comprises laparoscopic total adrenalectomy but innovative treatment such as RadioFrequency Ablation (RFA) constitutes an emerging promising alternative to surgery. The main aim of this study is to analyse the cost of RFA versus surgery on aldosterone-producing adenoma patient from the French National Health Insurance (FNHI) perspective...

BACKGROUND: Minimally invasive operative approaches for resection and thermal ablation (eg, microwave, radiofrequency) of hepatocellular carcinoma (HCC) have been successfully implemented over the last two decades, although identifying tumors can be challenging. Successfully performing laparoscopic ablation requires real-time visualization and ultrasonography skills for direct placement of the ablation probe. METHODS: In this study, we introduce a novel adjunct to ultrasound imaging for tumors located near or on the surface of the liver via intravenous delivery of indocyanine green (ICG) dye...

Background: Echinococcosis (E) is a zoonotic parasitic disease caused by the larval morphology of echinococcosis tapeworms. Among the recognized species, two are of medical importance-E. granulosus and E. multilocularis-causing cystic echinococcosis (CE) and alveolar echinococcosis (AE) in humans, respectively. Diagnosis of AE is based on clinical manifestation and epidemiological data, imaging techniques, histopathology and/or nucleic acid detection, and serology. At present, WHO guidelines suggest that benzimidazoles (BMZ) are mandatory in all AE patients, temporarily after complete resection of the lesions and for life in all other AE cases...

BACKGROUND: Factor V (FV) deficiency is an extremely rare disease, with an incidence of 1 in 1 million. The bleeding symptoms are mild, and the prognosis is good; however, the safety of surgical treatment is unclear, because there are few available reports. Herein, we report a case of hepatocellular carcinoma with congenital FV deficiency in a patient who safely underwent laparoscopic hepatectomy. CASE PRESENTATION: A 79-year-old man, diagnosed with hepatocellular carcinoma of liver segment 5, with type C cirrhosis and sustained virological response visited our hospital...

Most pancreatic carcinoma is ductal adenocarcinoma. Primary pancreatic clear cell carcinomas composed almost entirely of clear tumor cells are very rare. We present a case of a 72-year-old man with a pancreatic mass, which was detected on abdominal computed tomography (CT). He had no symptoms and no abnormal findings on physical examination; however, he had a history of hepatitis B, hepatitis C, and hepatocellular carcinoma. He had received anti-viral treatment and radiofrequency ablation twice until 2 years prior...

Radiofrequency ablation (RFA) may be used to treat either benign or malignant tumors of the liver. Complications are relatively rare, with the most common being pyogenic liver abscess formation. Risk factors for pyogenic liver abscess formation include Child-Pugh class B or C cirrhosis, biliary tract disease, diabetes mellitus, and preexisting biliary diversion. Differentiating sterile post-ablative necrosis from abscess formation may be difficult on imaging as air may be considered a normal post-ablation finding...

BACKGROUND: Radiofrequency ablation (RFA) is an effective treatment for early-stage hepatocellular carcinoma (HCC). Although RFA is a relatively safe technique compared with surgery, several complications have been reported to be following/accompanying this treatment. Delayed diaphragmatic hernia caused by RFA is rare; however, the best surgical approach for its treatment is uncertain. We present a case of laparoscopic repair of diaphragmatic hernia due to RFA. CASE SUMMARY: An 80-year-old woman with segment VIII HCC was treated twice in 5 years with RFA; 28 mo after the second RFA, the patient complained of right hypochondriac pain...

PURPOSE: This study aims to evaluate the value of the clinical application of ultrasound-guided percutaneous thermal ablation in focal nodular hyperplasia (FNH) by comparing its safety, effectiveness, and patient experience to surgery in the treatment of hepatic FNH ≤5 cm. METHOD: This retrospective study enrolled 82 patients with hepatic FNH having a maximum diameter of ≤5 cm, confirmed by postoperative pathologic diagnosis or needle biopsy, who underwent thermal ablation or surgery between January 2019 and September 2021...

Background: Radiofrequency ablation (RFA) has been used to treat various abdominal tumors including pancreatic tumors. Multiple approaches such as laparoscopic, open, and percutaneous have been used for pancreatic tissue ablation. More recently, endoscopic ultrasound (EUS)-guided RFA has emerged as a new technique for pancreatic tissue ablation. The role of EUS-RFA in management of pancreatic lesions is still not well-established. In this study, our aim is to assess efficacy and safety of EUS-RFA for management of pancreatic lesions...

Introduction: The J-Plasma has recently been introduced into the surgical community with different intrinsic characteristics aimed to further reduce the thermal effect and enhance precision when compared to standard radiofrequency. This study aimed to investigate the role of this new technology in different conditions of gynecological carcinomatosis characterized by the indication for regional peritonectomy and/or ablation, either in laparotomy (LPT) or in laparoscopy (LPS), in the context of a modern personalized approach to the surgical management of gynecological malignancies...

Postoperative inguinal neuralgia is a known complication of open or laparoscopic herniorrhaphy, initially managed conservatively with analgesics. If symptoms do not resolve additional treatment modalities include nerve blocks, mesh explanation, neurectomy or radiofrequency ablation. Radiofrequency ablation is also used for ablation of hepatic tumors, and thermal injury to bowel is a known and well-documented complication with its use on the liver. There is no published literature or case reports describing thermal injury to bowel from radiofrequency ablation of ilioinguinal or iliohypogastric nerves...

BACKGROUND: Minimally invasive partial nephrectomy (MIPN) and focal therapy (FT) are popular trends for small renal masses (SRMs). However, there is currently no systematic comparison between MIPN and FT of SRMs. Therefore, we systematically study the perioperative, renal functional, and oncologic outcomes of MIPN and FT in SRMs. METHODS: We have searched the Embase, Cochrane Library, and PubMed for articles between MIPN (robot-assisted partial nephrectomy and laparoscopic partial nephrectomy) and FT {radiofrequency ablation (RFA), microwave ablation (MWA), cryoablation (CA), irreversible electroporation, non-thermal [irreversible electroporation (IRE)] ablation, and stereotactic body radiation therapy (SBRT)}...

RATIONALE: Few cases have been reported of the coexistence of tuberculosis and adenocarcinoma of the large bowel. We report a rare case of concurrent ascending colon adenocarcinoma and ileocecal tuberculosis, which were nearly indistinguishable from one another. PATIENT CONCERNS: A 59-year-old man visited our clinic with dizziness and anorexia. DIAGNOSIS: Computed tomography revealed a mass in the ascending colon with ill-defined nodules in the liver...

BACKGROUND: Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant tumor syndrome with a high degree of heterogeneity in clinical phenotypes, generally involving the parathyroid, anterior pituitary, and enteropancreas. In recent years, several new insights into the clinical features of MEN1 have been reported in the literature. However, it is not clear whether MEN1-associated primary tumors can occur in the liver. CASE PRESENTATION: We report the case of a 52-year-old man with multiple endocrine neoplasia type 1 diagnosed by genetic sequencing...
